指标: ATR 概率水平
很棒的指标！我使用缓冲区创建了同样的指标，有没有办法绘制每天的支撑位和阻力位，而不是只有当天的支撑位和阻力位？
这是我目前的版本。但我找不到为每个"当前时间框架"条形图获取 10 天的日线条形图的方法......

请给我一个 mt4 版本。
xy618z 水平线 改为短水平线，只显示右侧。
您好
您可以尝试使用
ObjectCreate(0,_name,OBJ_HLINE,0,0,0);
和开始时间 + 'n' 作为停止时间。
水平线总是在整个图表上展开 - 您不能用时间参数来限制它 :https://www.mql5.com/zh/docs/constants/objectconstants/enum_object/obj_hline

谢谢。
无法编译有 4 个错误
ATR 概率水平:
基于 ATR 的概率水平。"概率" 是通过投射过的平均真实范围指标和之前时间段的收盘价来计算的。
